Our gravitational force calculator applies Newton's law of universal gravitation to determine the attractive force between any two masses. The calculation uses the fundamental physics equationF = G × m₁ × m₂ / r² with automatic unit conversions and scientific notation formatting.

Gravitational force is one of the four fundamental forces in nature. It's always attractive, acts instantaneously over infinite distances, and is proportional to mass while following an inverse square law with distance. This makes gravity unique among the fundamental forces.

• Gravity is always attractive - masses never repel each other
• Force follows inverse square law - doubling distance quarters the force
• Gravitational constant G is universal and extremely small
• Force acts along the line connecting the centers of mass
• Principle of superposition applies for multiple masses
• Gravity dominates at large scales despite being the weakest force
